You may also want to make sure that you use a newer version of software than Fedora Core 1.
I would suggest you download and install CenOS4.3; it's a clone of RHEL4, which means it's stable and secure,

Can you give some information about the server itself; ie. what speed is the processor.

From the screenshots of TOP, it is clear that your memory on the server is too low since it is using the swap space. Typically, you don't ever want your server to use swap space.

My initial recommendation would be to upgrade your RAM to at least 1GB.

The High load reported at the moment is definately because your system is trying to play catch-up because it uses hard drive space as virtual memory. It's unfortunately difficult to say which process started the high memory usage. It's possible that an application could have a memory leak, and that is what causes the server to start swapping in the first place. Best way to monitor that is top keep an eye on top as the server reboots. In theory, if your CPU is adequate, and your hard drives are not slouches ( preferably SCSI or SATA2) 512MB ram should be enough for plenty of websites and services.

Can you give us an indication of how busy the websites are that runs on your servers? It might also simply be that they are receiving lots of hits, and that will unfortunately cause high resource usage. Only remedy there is a bigger server...

You can also read up on www.apache.org and www.mysql.com on how to tweak the particular services for high-loads - but like I said already, throw in at least 512MB of RAM ( it's cheap and easy) and see where that get's you...

Well, in that case it seems that an upgrade might be the only solution here. The websites themselves (ie. the way they were coded) can also play a role. If the content are all dynamically created, stored and served from MySQL, then load will also be higher than having "static" html pages.

My initial recommendation stands; try to add more RAM and see if it helps. It's a quick, cheap and simple way to address resource usage. If that does not help, then either tweak the server software, or do a complete upgrade to a faster CPU, much more RAM and fast SCSI Harddrives.

Manage projects of all sizes how you want. Great for personal to-do lists, project milestones, team priorities and launch plans.
- Combine task lists, docs, spreadsheets, and chat in one
- View and edit from mobile/offline
- Cut down on emails

Those snippets look like an ISP price list options for a co-location/managed server at their server farm, am I right?

Another option that works out cheaper and takes away the hassle of having to look after the hardware and upgrade when things run slow, is to see if they have a "reseller" shared hosting package.

Those packages gives you your own space on one of their servers which you can allocate as you please to your domains, but the nice thing is; the ISP has to deal with the head-ache of making sure the server is fast enough/has enough ram for all the domains running on it, else they will lose their clients...

You may also want to make sure that you use a newer version of software than Fedora Core 1.

I would suggest you download and install CenOS4.3; it's a clone of RHEL4, which means it's stable and secure, and being a RedHat clone, means that you should find it operting pretty much the same as Fedora wrt file locations etc...

This document is written for Red Hat Enterprise Linux AS release 4 and ORACLE 10g. Earlier releases can be installed using this document as well however there are some additional steps for packages to be installed see Metalink.
